And even salted peanut butter still has about twice as much potassium as sodium.Numerous studies have shown that people who regularly include nuts or peanut butter in their diets are less likely to develop heart disease or type 2 diabetes than those who rarely eat nuts.
We Live in a Radioactive World The uses of radioactive materials, many of which generate low-level radioactive waste, have become an integral part of modern life. We do live in a radioactive world. Radioactivity is all around us. It is in rocks, in soil, in water.
1 Most rocks have tiny amounts of radioactive material in them. 2  Radioactive elements decay (they change into a completely different element -- for example, Uranium which is used in nuclear reactors changes into Lead, a very dense metal).
